Wi-Fi Data Loggers Support Bluetooth For IoT Apps

To monitor, collect and share temperature data wirelessly, T&D Corporation’s TR-7wb Series Wi-Fi-connected data loggers are now equipped with Bluetooth to access mobile devices through the T&D Thermo dedicated mobile app. The series supports multiple sensors and comes in four models: TR-71wb, TR-72wb, TR-72wb-S and TR-75wb.


The data loggers connect seamlessly to T&D’s cloud-based WebStorage Service via Wi-Fi and through the T&D Thermo app, both provided free of charge. Measured data can now be automatically uploaded, stored and viewable on mobile devices anytime and from anywhere. The T&D Thermo app was also recently redesigned to add Bluetooth connectivity and provide an improved user interface for quicker access to critical data.

Analog Devices ADIS16500/05/07 Precision Miniature MEMS IMU Available Now from Digi-Key

The Analog Devices’ ADI ADIS16500/05/07 precision miniature MEMS IMU includes a triaxial gyroscope and a triaxial accelerometer. Each inertial sensor in the MEMS IMU combines with signal conditioning that optimizes dynamic performance.


The compact, battery-powered devices retain all the features of the original TR-7wf Series and can be deployed in virtually any quantity to form a unified data reporting network, connected to the internet via Wi-Fi, or through a Smart Device using Bluetooth. Other features of the TR-7wb series include:

  • The TR-71wb model utilizes two external interchangeable sensors which have a temperature range of -40 to 110°C and a temperature accuracy of + or – 0.3°C.
  • The TR-72wb model utilizes a THA-3001 sensor which has a temperature range of 0 to 55°C, a humidity range of 10 to 95 percent RH humidity range, a temperature accuracy of + or _ 0.5°C and a humidity accuracy of + or – five percent.
  • The TR-72wb-S model utilizes the brand-new SHA-3151 sensor which has a temperature range of -25 to 70°C, a humidity range of zero to 99 percent RH, a temperature accuracy of + or _ 0.3°C and a humidity accuracy of + or – two and a half percent.
  • The TR-75wb model is compatible with the following Thermocouple sensors (K, J, T, E, S, R) and has a temperature range of -199 to 1760° C.  Type K, J, T and E sensors have a temperature accuracy of + or - (0.5°C + 0.3 percent of reading), while the type S and R sensors have a temperature accuracy of + or - (1.5°C + 0.3 percent of reading).
